While I am sure the NIST-Fx fountain clocks use laser cooling as a way to read cesium atoms' output more accurately, is it not true that the major advance in the fountain clock is the fact that atoms are propelled in an upward direction in order that GRAVITY will slow them down, too, as the atoms reach the apex of their travel?
